I am getting an error while re-deploying an ear file. This ear
was deployed earlier and was working fine for two months. Due to
some reasons it stopped subscribing messages. So I undeployed
and tried to redeploy. But I couldn’t do due to the below
reasons.

Hi LOkhi,
Go to the appication configuration section of your
deployment in Administrator . Check the RvDaemon,RvNetwork,RvService
parameters carefully.
After the deployment the paramaters have been
overriden or changed it seems.

Update these variables carefully as per your network
and transport settings used by your application and then start the
engine.
